Abstract

The invention relates to an 'AC-AC (alternating current) regulation and control' based numerical-control HID (high intensity discharge) driving method and a driver applying the same. The numerical-control HID driving method is implemented by direct AC-to-AC power switching. In the numerical-control HID driving method, an embedded controller and an 'AC-AC regulation and control' driving module are used as the core which is connected with various circuits, input sinusoidal AC is subjected to AC modulation directly, a constant-power sinusoidal AC power source meeting requirements for numerical-control HID driving is output, and various lighting functions and control protecting functions under the numerical-control HID driving are realized. The driver is a circuit device applying the numerical-control HID driving method, and a circuit of the driver comprises an EMI (electromagnetic interference) and input filter circuit 2, an AC sinusoidal output filter circuit 4, a current and voltage sampling feedback circuit 5, a high-voltage trigger driving module 6, a communication control interface circuit 7, an HID bulb 8 and an input AC power source 9. The driver is characterized by further comprising the embedded controller 1 and the AC-AC regulation and control driving module 3.
